Answer:
x = 5
Step-by-step explanation:
4x - 3 = 2x + 7
4x - 2x = 7 + 3
2x = 10
x = 10/2
If you're solving for d your answer is d = -t,rt
If you're evaluating the problem your answer is t = d/r
If you're solving in terms of arbitrary letter d your answer is r=d/t
I hope this helps!
Oranges = x dollars
apples = x+3 dollars
An equation is
Oranges + Apples = 10 dollars, or
x + (x+3) = 10
2x = 10-3
2x = 7
x = 7/2 = 3.5
ANSWER. Sara spent $3.50 for oranges.
Is this good ?

Let one of those even numbers be x, Then other even number would be x + 2.
<u>According</u><u> </u><u>to</u><u> </u><u>question</u><u>,</u>
⇛ Their reciprocal add upto 3/4
<u>So</u><u>,</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>write</u><u> </u><u>it</u><u> </u><u>as</u><u>,</u>
⇛ 1/x + 1/x + 2 = 3/4
⇛ x + 2 + x / x(x + 2) = 3/4
⇛ 2x + 2 / x² + 2x = 3/4
<u>Cross</u><u> </u><u>multiplying</u><u>,</u>
⇛ 3(x² + 2x) = 4(2x + 2)
⇛ 3x² + 6x = 8x + 8
⇛ 3x² - 2x - 8 = 0
⇛ 3x² - 6x + 4x - 8 = 0
⇛ 3x(x - 2) + 4(x - 2) = 0
⇛ (3x + 4)(x - 2) = 0
Then, x = -4/3 or 2
☃️ It can't be -4/3 because it is fraction and negative number. So, x = 2
Then, x + 2 = 4
✤ <u>So</u><u>,</u><u> </u><u>The</u><u> </u><u>even</u><u> </u><u>numbers</u><u> </u><u>are</u><u> </u><u>2</u><u> </u><u>and</u><u> </u><u>4</u><u>.</u>
